Inventory script to gracefully handle AWS being down

Help git module work when working in 'no branch' scenario

Detect when on a 'no branch' branch.  If so, checkout the HEAD branch
as reported by 'git remote show <remote>'.  That should put the repo
back on a branch such that git can then merge changes as necessary.
In addition, removed hard-coded references to origin and replaced
with remote var.

Reverting as this as reported allows some variables to clobber each other.
We'll work on a different fix.

This reverts commit c5469f63.

Clarify how only_if works, also combined with with_items

- The old documentation stated not to quote the variable in the function, which is obviously wrong. When using lists or integers, we have to quote otherwise the startswith() method will trip over its non-existence.
- It was unclear that the only_if statement is processed for each item when doing with_items, so I added an example making it crystal clear how this can be used in your advantage (or why a non-existing list variable can break your logic if you expected the only_if to be processed once before running the task)

Fix ansible_ssh_host again

This time with unit tests to ensure it keeps working.

Added some info on the unit tests requirements

Various performance streamlining and making the file features usable in all modules without daisy chaining.

Adds release date for Cathedral

I also prepended each single digit month with a 0 for the dates to line up. Feel free to change that :) 

Added 'script', a module that can push and insantly run a remote script.  Replaces the need to copy+command.

This is a bit of a rough draft, some error handling still needs to be added.

Add ability to create SSH key for user in user module

add role_attr_flags parameter to postgresql_user

Vars specified via CLI have the highest priority.

This allows one to create a SSH key for user.  You may define:
ssh_key_type, ssh_key_bits, ssh_key_file, ssh_key_comment,
and ssh_key_passphrase.  If no passphrase is provided, the
key will be passphrase-less.  This will not overwrite an existing key.
In the JSON returned, it will provide the ssh_fingerprint and
ssh_key_file.

make policy only be required if state is not disabled

Update Hadoop contrib URL.

when a pkg is installed, but not from any repo, don't error out

that it is not installed.

Also when a pkg is both installed and in a repo do not look it up
more than once

References issue #1380.
